Tomato and Tobacco Hornworms are green caterpillars usually 3-5 inches long that love to eat tomato leaves and stems. The Tobacco hornworm has 7 diagonal white stripes on each side of its body and a red horn on its back end. The Tomato hornworm has white “V” shaped markings with a black horn on its back end. Both hornworms have five pairs of prolegs, which are soft legs that are on the abdominal segment of the body.

 
They can blend in so well with the green leaves of your tomato plant, you may not even notice them; however, you will notice the  damage to the leaves and stems. They will eat holes in the leaves and at times eat the entire leaf leaving no stems.  During July and August they might even chew on the fruit of tomatoes and eggplants. Tomato hornworms have also been known to eat peppers and potatoes.

How do I know if I have Hornworms?

You will most likely spot the damaged leaves and stems at the top of the plant before you spot the hornworm. Hornworms will feed on the inside of the plant during hot sunny days and move to the outside in the morning and evening. You may notice large, black droppings (frass) that will pile up on the ground below the affected plants.

 
How do I get rid of Hornworms?

Pick them off using gloves and crush them with your foot or cut them in half with a garden tool.

If your Hornworm has small white cocoons attached to its body then leave them alone. The cocoons contain the larvae of a parasitic wasp that is a natural parasite of the hornworm. The wasps will kill the hornworms when they come out of their cocoons and search out other hornworms to attack.

Rototilling your garden after the season will kill the larvae that has burrowed into the soil of your garden.

Vegetable Gardening: A Report from the Furrows

This year we had a bounty of cucumbers, and so, we also had a bounty of cucumber seeds.

Now, what to do with those seeds?

No, we are not going to spit them at our little sister…tempting perhaps, but no. There are much better uses for cucumber seeds:

One of the smartest things to do would be to save them for next year. Storing seeds is both a wise and economical choice. Instead of buying the cucumber seedlings from a nursery or a garden center, you can grow your own. It not only saves you some money, but the tiny seedlings are fun to watch grow, especially know that they are your very own.

To store your seeds until next season –

• Remove them from the plant gently and wash them, make sure you get any plant debris off of them.
• After that, take an air-tight jar and put the seeds in it. You can also add a packet of silica gel (you know those strange packets you often find in the pocket of a new suitcase or purse) to absorb any moisture.
• Next you need a nice cool place for them. It is essential that the spot you keep them in is dry and dark, otherwise the seeds will rot and you will end up with a cucumber shortage. A basement is a good spot – as long as it is not too damp. Another good spot is in the refrigerator, if you can spare the space, as the cold temperature will help preserve them.

What if you forget about your cucumber seeds in the back of the fridge next year?

Well, just in case you don’t plant the cucumber seeds next year, not to worry. They are good for up to four years.

***However, the older the seed, the longer it might take to germinate and the plants may not be as strong as they could be. So, its best to replenish your seed stock freshly every year.
